I was just told by China Post that Shipping that normally took two weeks will now take a month. They couldn't/wouldn't tell me why, but that means that shipping will now take longer to get to its destination.

So far it seems EMS shipping time hasn't been affected much. But other shipping methods from China actually never seem fast to me. From what I got in the past, 4 weeks is just a starting point. But I guess it's faster if it's from eastern cities of China to the west coast of US, and when the security check is not strict and slow on every parcel.
